A)What does the point (9,90) mean on this graph? Be specific using the titles of the axis.
Your answer:
B)Choose 2 points on the graph and list them below. (X,Y)
( , ) and ( , )
C)Find the slope of the line on the graph using your chosen points. Remember to use RISE / RUN. Simplify your slope. The graph doesn’t count by ones! Use the values on the graph to find the slope.
Your answer:
Drag the blue points and the red lines onto the graph to show your slope for part B and C
A) The point (9,90) means that the value of the dependent variable (Y) is 90 when the value of the independent variable (X) is 9.
B) Two points on the graph could be (3,30) and (6,60).
C) To find the slope of the line, we use the formula: slope = (change in Y) / (change in X). Using the points (3,30) and (6,60), the change in Y is 60 - 30 = 30 and the change in X is 6 - 3 = 3. So, the slope is 30 / 3 = 10.
Explanation for the graph:
In the given graph, drag the blue points to the coordinates of the chosen points (3,30) and (6,60). Then, drag the red lines to connect the blue points and show the slope of 10.
